Comment (by pramsey):

 The current problem seems to be strongly associated with the
 `rtpg_assignHookGDALEnabledDrivers` function. In 2.0 to 2.1 it was called
 in `_PG_init()` directly to read the environment variables and set up GDAL
 drivers the user wants.

 If you remove calls to `rtpg_assignHookGDALEnabledDrivers` in 2.3/svn, you
 can get a clean upgrade from 2.1, no hang. If you change the call to
 `rtpg_assignHookGDALEnabledDrivers` in 2.3/svn from a callback in the GUC
 setting function to a direct call in `_PG_init()` you can **also** get a
 clean upgrade from 2.1, no hang.
